Probe for detection of biological signal



FIG. 1 is a front elevational view of a first embodiment of a probe for detection of biological signal;

FIG. 2 is a rear elevational view of the first embodiment thereof;

FIG. 3 is a right side elevational view of the first embodiment thereof;

FIG. 4 is a left side elevational view of the first embodiment thereof;

FIG. 5 is a top plan view of the first embodiment thereof;

FIG. 6 is a bottom plan view of the first embodiment thereof;

FIG. 7 is a cross-sectional view of the first embodiment taken along the line 7-7 in FIG. 1;

FIG. 8 is a perspective reference view of the first embodiment thereof;

FIG. 9 is a front elevational view of a second embodiment of a probe for detection of biological signal;

FIG. 10 is a rear elevational view of the second embodiment thereof;

FIG. 11 is a right side elevational view of the second embodiment thereof;

FIG. 12 is a left side elevational view of the second embodiment thereof;

FIG. 13 is a top plan view of the second embodiment thereof;

FIG. 14 is a bottom plan view of the second embodiment thereof;

FIG. 15 is a cross-sectional view of the second embodiment taken along the line 15-15 in FIG. 9; and,

FIG. 16 is a perspective reference view of the second embodiment thereof.

The broken lines set forth in the figures illustrate a light source and a light sensor on a front surface of the probe, a disclaimed line along the outer perimeter of the probe, and a connecting cable and main unit with which the probe is used. The broken lines form no part of the claimed design. 

CLAIM The design for a probe for detection of biological signal, as shown and described.
